To all w/wlw [It TIMI/f] concern:

Be it knowntha't l, Jonn E. BELL, of Bar-- berton, Summit county, ()hio, have invented a new and useful Superhcator-Boiler, of which the following is a full, clear, and exact description, rel'erence being had to the accompanying drawings, l'orming part of this specification, in .whi(-.l1--

Figure l is a diagrammatic cross-section ol" a superheater boiler constructed in accordance with my invention; Fig. 2 is a sectional side elevation of the same; Figs. 3 and 4 are views similar to Figs. 1 and 2, showing a modified form; Figs. 5 and 6 are views simi lar to l igs. l and 2, showing another form; Fig. 7 is a View similar to Fig. 6 showing a 'modilhation ot' the I'orm of Fi 5 and Fi s.

S and it are views similar to Figs. 1 and 2 respectively, showing another arrangement of lurnace and battles.

My invention relates to the class of water tube boilers having longitudinal upper and lower drums, the gases passing longitudi nally of the drums.

The invention is designed to combine a superheater with such a type of boiler in an ellicicnt and economical manner.

In the drawings, referring to the term of Figs 1 and 2, 2 represents a longitudinal steam and water drum, and I; a longitudinal parallel mud drum, 4 is the front wall and the rear wall of the setting, ti the otl'take and 7 the furnace, 8 is the roof or arch of the combustion chamber which extends rearwardly a portion of the length ot'the mud drum, and is provided with a narrow battle extension. 9 beneath the remaining portion ol" the mud drum, leaving ports 10, 10 opening upwardly on each side of the drum 3 at its rearv 7 1 1 is a battle which extends upwardly between the water tubes 12 which connect the steam and water drum with the mud drum, and 12; is a depending baille in front of the water tubes.

In line with the baffle 13 the steam and water drum is provided with a transverse partition 14 having a connecting hole or opening 15 in its upper portion, while the mud drum has a corresponding separating,

partition 16. In the front of these partitions, the two drums are connected by superheater tubes 17. These tubes are divided into I two sets by a separating partition 18 in the upper drum.

In the use ol the apparatus the (lame and gases rise around the rear part of the mud drum, [low up among the tubes 12 to the top of the batlle ll, thence down among the other water tubes to the lower end of the ballle 13, and thence up among the superheating tubes to the oll'take 6. The steam generated in the steam and water drum llows through the. hole 15 into the stream compartnu-nt, and thence down through one set of super-heating tubes and up through the other set of superheating tubes into the outer steam mmpartment where it is taken oil' through outlet 19.

In Figs. 3 and 4 I show a similar appara tus except that two steam and water d'rums 2" are provided,each connected by the tubes 12 to the single mud drum 3. Each of the upper drums is provided with partitions as shown in Figs. 1 and 2, similar parts being indicated by similar numerals with the letter (1 ap )lied.

' In Figs. 5 and 6 I show a form similar to Fig. 1, except that three steam and water drums 2 are provided cor nected by the tubes 12" to the single muddrum 3.

In Fig. 7 I show a form similarto that of Fig. :3, except that the superheater tubes 1'7 are located in the middle pass of the gases. In this case in addition to the apertured partitions 14" of the upper drum, they areprovided with the partition 18" and a third separating partition 20. The partition 20 is connected to the partition 18 by an upper tube 21 so that the steam generated in the front water compartment may pass to the compartment between the partitions 14 and 18*. The lower drum is provided with a second partition 22 and Water tubes extend between the partitions 16 and 22 and between the lower parts of the pm'titions 14" and. .20 of the steam and Water drum.

in the form of Figs. h and t) the furnace 7 is exterior to the setting at one end. The llamc and gases from the turnaee pass-in among the tubes 12" and are given three up and down passes the same as in Figs. 1 and 2. The partition of the drums and the general arrangement is the same as that of l igs. 1 and 2, similar parts being designated by similar numerals with the letter (Z applied.

The advantages of my invention result preferably used give the gases up and down passes, and the first pass is preferably entirely occupied by water tubes to prevent injury to the superheating tubes. An efiicient and economical apparatus is thus provided in Which the steam is produced and-superheated in the same setting. 7

The superheaters may be provided with return-bend or U-shaped tubes, the arrange 'ment of the drums may be varied, and many other changes may be made without departing from my invention.

I claim 1. A water tube boiler having upper and lower longitudinal drums connected by water tubes, means for passing gases longitudinally of the drums, and a superheater in the boiler structure and connected to the steam space of the boiler, said boiler having water-heating tubes between the source of heat and the superheater, substantially as described. 2. A water tube boiler having upperand lower longitudinal drums connected by water tubes, bafiles arranged to give the gases up and down tudinally o' the drums, and a superheater located in the boiler setting, said superheater being exposed to the heat of the gases and connected to the steam space of the boiler, said boiler having water-heating tubes between the source of heat and the superheater substantially as described.
